air filter housing o-ring RRC3746

So I have my air filter housing out while I was running my power steering lines. I noticed that the seal/o-ring has seen better days.

It looks like it is supposed to be part number RRC3746, but that is NLA as far as I can tell. This is on a 2.5NA

Do I just not worry about it, and make do without it or with whatever chunks will go back in, or is there some alternative? I know it's not a huge deal because the filter seems to seal to the upper part of the housing where the intake tube connects, so it shouldn't be an issue of dirt getting into the engine, this seal is just for the two parts of the housing.

It does not do much unless you had a snorkel. You could make one with an o-ring kit, or use weather stripping, or silicone if you wanted.

I'm having better luck with this one than my LR3. I got a new update for my scan tool that allows it to work on newer land rovers, and I flashed some of the computers with good success. Then I flashed the transfer case control module..... and now it's forgotten everything it once knew. And they scanner does not have a calibration routine for this. (yet, I hope)

I might be driving the 90 for a few days, just so I don't risk damaging anything.

Some of the places in the UK show it, but I don't know if that really means they can get it or not. I just google the part number and some sites came back. I may put it on an order if I order some other stuff and see what happens.

Have you tried a hardware store? Any idea what the actual size is, I'm not near my truck right now.

Mcmaster has every size of o-ring you can imagine.

I got one for my air filter housing there a few months ago.

Cheers
